Definitions

  • the invention is based on a printing method in which the printing process is carried out with at least one printing fluid through a plurality of narrow and closely spaced nozzles.
  • Narrow nozzles are understood to mean those with an opening diameter of a few micrometers and as narrow distances which are of the order of magnitude of 100 micrometers.
  • the invention relates to the aspect of security against forgery of prints.
  • Piezo elements are deformed by means of electrical voltage pulses, as a result of which a pressure surge is generated in the ink channel or in the ink chamber in front of the nozzle, and an ink drop is thereby sprayed out of the nozzle.
  • piezo elements used, such as tubes, plates or lamellae.
  • the Piezo-Mach technology used in the printer with the type designation Stylus 800 from Epson, in which the piezo slats of a row of nozzles are arranged in a block (multilayer), enables a very small distance between the individually controllable nozzles a printhead.

Abstract

L'invention concerne un procédé d'impression selon lequel l'opération d'impression est réalisée avec au moins un liquide d'impression à l'aide de plusieurs buses étroites et proches les unes des autres. Les buses sont commandées individuellement ou par groupes en termes de projection/de non projection de liquide d'impression suivant une règle secrète, ce qui permet de créer des modèles secrets de réseaux de pixels qui peuvent être modifiés pendant l'impression selon une règle secrète ou renouvelés à différentes distances secrètes. En raison des buses étroites et proches les unes des autres de la tête d'impression, Ces modèles peuvent avoir une dimension qui exclut toute détection d'un modèle à l'oeil nu.
